8 Claims.

Our invention relates to a mechanism. for efliciently applying rolled sheet material to vertical surfaces. More particularly our invention relates to a mechanism for applying relatively heavy paper rapidly and efiiciently to the walls of a shipping compartment, as in freight cars or ships, said paper being caused to extend close to the floor and around the corners, especially in preparing the car for shipping flour to avoid contamination of the same.

For purposes of definiteness and clearness of illustration, we will set forth our application as applied to the preparing of a shipping compartment, as in a freight car, truck or ship, in which sacked flour is'to be transported.

While the optimum advantages of the mechanism embodying our invention may be obtained from its use in applying rolled sheet material to vertical surfaces, nevertheless it has itsadvantages in maneuvering a roll of relatively heavy sheet material while securing therefrom strips of sheet material to be applied to the floor or ceiling. The deviceis applicable to facilitating the lining of shipping compartments either from the size of relatively small containers to freight cars or compartments of a ship or truck. Furthermore, manifestly the device is well adapted to applying sheet material to the exterior of containers, the contents of which require special protection.

At the present time, a roll of heavy paper, some nine inches in diameter by sixty inches long, is manually moved about the car, while the paper is being unwound and secured to the wall of. a car by appropriately located applications of glue. Such operation requires considerable time of two or more operators. Since the roll of paper may weigh one hundred pounds or more, it is obvious that such manual handling is tiring and results in inefficiency.

One of the problems presented is to have the paper or sheet material extend in close proximity to the floorv of the car when secured in place. On one face of the machine, the paper mustbe freeto move out to the wall and thecastors supporting the base member must beof a size to permit easy rolling over relatively rough surfaces, that is, these considerations establish conflicting conditions, as the bottom edge of the paper must extend in close proximity to the floor while the proper size of the castors operates to require the base to be considerably above the floor. Also, it is a requirement that the device be constructed so that the'paper may be applied inthe corners of a shipping compartment. While the roll of paper must be so mounted that it may be freely unwound, nevertheless friction on the edge of the sheet must be avoided. On the other hand, it must not be free to unwind faster than is desired.

A primary object of our invention is to pro-. vide a mechanism economical in manufacture and one characterized by the ease with which it may be conveniently and efficiently moved about so that the period of application of the paper to the surface for such papering is greatly reduced. Also, it is a primary object of our invention to provide an upper spindle of such construction which will permit of ready installation of the roll of sheet material in operative position within the mechanism. Further, an object of our invention is to provide a turntable mounting sumciently close to the floor and this in conjunction with a yielding brake action that will provide an operative mechanism and will fully overcome said difliculties.

The above mentioned general objects of our invention, together with others inherent in the same, are attained by the mechanism illustrated in the following drawings, throughout which drawings like reference numerals indicate like parts:

Figure 1 is a front view in elevation of a mechanism which embodies our invention;

Fig. 2 is a view of the same in the direction of arrows on line 2-2 of Fig. 1;

Fig. 3 is a plan View of said mechanism;

Fig. i is a view of a base member of the same;

Fig. 5 is a view in perspective of a carriage for subtending the lower spindle as respects the base member l9;

Fig. 6 is a view of the-top spindle in said mechanism for mounting a roll of paper; and

Fig. 7 is a view of the lower spindle in said mechanism for mounting a roll of paper.

On a base member id is mounted an upright frame I i preferably formedoi' tubing welded together comprising upright tubes l2, l3, l4, l5 and It arranged in a triangular form having top links or members I7 and 18 forming legs. of a triangle with the apex 19 and link or member 20 extending across the front to complete the triangle. The base member It is supported by castors 2i.

On the one hand, it is important to have the castors of such size that they will permit rolling over relatively rough surfaces. At the same time, the roll 34 of paper must be capable of being run out on one side to be applied to a wall, and the paper must extend in close proximity to the floor on said wall. To permit the castors to be of suflicient size and at the same time permit the paper to be secured on the wall in close proximity to the floor, the lower spindle must be located close to the plane of the bottom of the castors.

The mounting for the lower spindle (see Fig. '7) is carried on plate 22 carried below the base member or plate I!) by tubular frame means 23. The spindle 24 is located in opening 25 in plate 22 on which plate 22 is welded a ring 26 within which ring is disposed a ball bearing means having inner race 2'! and outer race 28. Outer race 28 is held stationary in ring 26 by means of set screw 29. The spindle 24 is held integrally with inner race 2'! and nut 30, by means of a lock washer 3| of standard construction. Nut 30 functions to clamp the parts together. Spindle 24 has flange 32 which rests on inner race 27. On this flange 32 is welded a turntable plate 33 on which a roll of paper 34 may be disposed by causing the upper portion of spindle 24 to protrude into the wooden bung 35 normally carried in the end portions of the roll of paper 34. It has been found highly important that the paper be mounted on a turntable so that the edges of the paper will not be subjected to friction of any consequence when the roll is being unwound.

A top spindle and its mounting is provided (see Fig. 6) as follows: A plate 36 secured in the front to frame member 29 and in the rear to frame member 31 has welded thereon a nut 38 having internal threads. A pin 39 extending through an opening 40 in plate 36 has secured on its upper end an enlarged threaded member 4|, the threads of which engage the internal threads of nut 38. On the top of member 4| is secured a short bar 42.

Leg member I! of the triangular frame (see Fig. 3) is longer than the other legs I8 and 20 of the triangle and is caused to serve as a vertical brush mounting member having vertical brush 43 which may press the paper 44 as it unrolls from the roll of paper 34 against the vertical wall 45. A resilient brake means for the roll of paper to prevent its unrolling except when desired is preferably provided by means of a diagonally disposed belt 46 having a spring mounting end member 41 secured to the upright member |2 of the frame while the opposite end 48 of belt 46 may be fixedly secured to upright IS.

The mode of operation of the device embodying our invention is as follows: The upper spindle is unwound by means of bar 42 and removed from the nut 38 so that the lower end of the roll of paper 34 may have its wooden bung 35 placed over the tapering end of the lower spindle 24 and the end of the roll caused to rest upon the turntable 33. Then the top of the roll is moved inwardly so that the axis of the roll is in line with the opening 40 of plate 36. Thereupon, the pin 39 is caused to be moved downwardly into the bung 39a in the upper end portion of the roll of paper 34 by turning the bar 42 to thread member 4| in nut member 38.

Applications of glue are then placed on the vertical surface to be covered, and the paper 44 is then pulled out and placed against the glue and the machine is then caused to run with its front substantially parallel with the vertical surface with the brush 43 pressing the paper against the wall 45. In Fig. 3 the machine would be moving to the right of the drawing, 1. e., in direction of arrow. When a corner of the shipping compartment is reached, it is manifest that the machine can be turned on its axis with the brush member 43 on its extended arm reaching into the corner of the compartment and pressing the paper into the corner itself. The paper is prevented from unrolling prematurely by means of the resilient brake means in the form of the belt 46 with its spring mounting ll-the opposite end 48 may be rigidly secured to its frame member as by riveting. The front of the machine is open from the bottom of the paper to its very top, the base plate l0 having an opening 49 on its front side so that the paper may run out freely over its entire width from the turntable plate 32 to the vertical surface being papered or covered. Having the lower spindle 24 suspendedly mounted, as respects base plate I0, provides for causing the paper to extend substantially to the floor.

The device provides a very eflicient means for handling the relatively heavy roll of paper and permits the same to be unrolled in a manner for quick application of the paper to the vertical surfaces of a shipping compartment, whether it be in a freight car or in a ship or truck. Also, having the paper mounted in a mechanism of this character which permits it to be wheeled about and maintained in a position for unrolling the paper, relieves the operators of much manual effort-a one hundred pound weight not only being heavy in itself, but in the form of a sixty inch roll of paper is very inconvenient to handle. The paper in our invention is free to be unrolled when desired and at the same time the unrolling of the paper is definitely controlled by the resilient or yielding brake means 46 against prematurely unrolling. The providing of a vertical brush 43 outside of the perimeter of the frame provides a construction for very readily pressing the paper into the corners of a shipping compartment. Instead of brush 43, a roller may be substituted.

Obviously, changes may be made in the forms, dimensions, and arrangement of the parts of our invention, without departing from the principle thereof, the above setting forth only a preferred form of embodiment.
